Neopixel-IR

This is a combined example code that does neopixel animations while listening for IR commands (given a capable enough chip)

It supports 6 different libraries, 2 for IR and 4 for Neopixels:

Supported/tested chips are:

  • basic AVRs like Uno/328p, Mega, Leonardo and so forth - they only allow concurrent IR if you remove interrupt disabling in the neopixel library, or you can update the neopixel strip and then listen for IR for a while.
  • Teensy v3.1 - this allows talking to neopixels while listening for IR
  • ESP8266 - also allows both thanks to esp8266_ws2812_i2s which doesn't tie up the CPU
  • ESP32 - also allows both thanks to ESP32-Digital-RGB-LED-Drivers/RMT which also doesn't tie up the CPU.
